What is "CleanLibrary" in a users profile folder?

Question

Lately with new 10.8/10.9 OS Macs we've been seeing a folder called "CleanLibrary" rather than the hidden library file for users that have hosted Home folders on a 10.8 server.  What is this, why don't they have the standard Library folder and why isn't it hidden like the standard Library folder?  Can't find an answer here in the discussions or strangly on Google.

Hi Laarse,
Thanks for the reply.
Please try enable “Do not forcefully unload the users registry at user logoff”
policy to check if it works. The Category path is
Computer Configuration\Administrative Templates\System\user Profiles\
After that, if the issue still exist, please collect below information for further research.

===============
1. Enable gpsvc debug logging by below steps:
In the Regedit Editor, expand HKLM\Software\Microsoft\Window NT\CurrentVersion
Create a new key called “Diagnostics”
Under the key, create a DWORD value “GPSvcDebugLevel” and set the value as
0x30002.
After making this change, restart the computer.
When the issue happens again, please send me the gpsvc.txt under %systemroot%\debug\UserMode folder.
Please let me know the time you experience this issue.
2. Please help run
gpresult /h c:\gpresult.html command on a problematic client, and send me the
gpresult.html file.
3. Please help collect profile trace on a problematic client by below steps:
Logon to a client with local administrator account.
Open a command prompt with ELEVATED.
Run "logman -start profile -p {eb7428f5-ab1f-4322-a4cc-1f1a9b2c5e98} 255 3 -ets" (without the quotes, if we face error, please do not use copy, manually input this
command)
Switch user (do not log off the administrator account) and try to logon with the problematic user to reproduce the symptom.
After you login, please logoff the domain user and back to local administrator account.
Run command
"logman -stop profile -ets" with administrator privilege.
Then send me the profile.etl under
%SystemRoot%\Debug\UserMode folder 
Thanks.
